The principle of equal apriori probabilities

Short description and context

The principle of equal apriori probabilities

Any physical system can adopt one of a number of microstates. For a quantum system these are the various quantum levels. For a classical system these are the various combinations of velocity and positions of the atoms in the system. Regardless, the set of all the possible microstates the system can adopt is known as

Syllabus Aims

  • You should be able to explain the meanings of the terms microstate and phase space.
